Title: Label magazine
Inventor: LEHMANN REINER
IPC: B65C9/10
Filed: 1987-09-26
Abstract: In the state of the art, the label stack located in a label magazine for labelling machines is loaded with pressure by spring motors, in order thereby to bring about the feed of the label stack. In order to make the feed pressure, exerted by the spring motors and necessarily varying over the entire path of the label stack, equal over the entire path of the label stack, there is proposed a drive which is designed as a pneumatic/magnetic piston/cylinder arrangement and which ensures that, irrespective of the length and weight of the label stack, the same pressure is always generated at the label-dispensing end and can be checked and regulated by pressure-measuring instruments, as seen over the travel of the magnetic piston.

Title: Directing device for an electric portable drill, and portable drill equipped with it
Inventor: KAMINSKI GERHARD PROF DR
IPC: B25H1/00
Filed: 1988-03-01
Abstract: In electric portable drills it is difficult to make the drill hole exactly perpendicularly or horizontally. This has a disadvantageous effect on the positional accuracy of objects inserted in the drill hole. The device is intended to make it easier to hold the drilling spindle exactly perpendicular or horizontal when making the drill hole. In order to be able to check the direction of the drilling spindle, at least one spirit level (tube spirit level and/or box spirit level) is arranged on the drill housing. The axis of the spirit level runs parallel to the axis of the drilling spindle. The device can be firmly connected to an electric portable drill or can be designed as a retrofit accessory. <IMAGE>

Title: Microgravitational ultra high-pressure melting method with high-speed cooling
Inventor: FOPPE WERNER
IPC: C22C1/02
Filed: 1989-01-30
Abstract: In the microgravitational ultra high-pressure melting method with high-speed cooling, use is made of the weightlessness caused in a reaction vessel in a state of free fall in an evacuated fall shaft of great depth and large diameter to produce new materials which have properties such as great hardness, high-temperature stability, corrosion resistance, thermal shock resistance, high thermal conductivity and similar properties, especially alloys, on an industrial scale under microgravitation without having to opt for the time-consuming and costly indirect means of space production, which is as yet not feasible. During the brief period of weightlessness (about 10 seconds), the material, which is in powder form, is melted by the energy source producing the melting heat and pressure, is compressed in evacuated moulds and is instantaneously cooled, preserving the melt structure present during the period of weightlessness. This method opens up new paths of materials research and industrial production of exotic materials in one operation from the melt to the finished workpiece.

Title: Plunger pump
Inventor: OBERMANN KLAUS
IPC: F04B9/105
Filed: 1989-04-07
Abstract: Hydrostatically driven plunger pump for conveying liquids loaded with abrasive particles. The plunger (14) of the plunger pump is coupled to a double-acting hydraulic piston-cylinder unit (16) which forms the drive and to which hydraulic medium is applied by means of hydraulic control members. Provision is made of devices to which pressure (hydraulic) fluid can be applied and by means of which the plunger-type cylinder (22) and the associated plunger (14) situated in the position in which the working stroke is extended to its maximum can additionally be moved apart relative to one another to such an extent that the plunger is completely withdrawn from the plunger-type cylinder and thus the seal which seals the plunger in the plunger-type cylinder is accessible for exchanging. The devices to which pressure fluid can be applied have for each plunger (14) and plunger-type cylinder (22) at least one, preferably a plurality of cylinder units (58) whose cylinders (56) and whose free piston rod end act, on the one hand, on the assigned plunger-type cylinder (22) and, on the other hand, on a component connected rigidly to the cylinder (42) of the hydraulic piston-cylinder unit (16) driving the respective plunger (14). The working space of the cylinder unit(s) which is active when the piston rod is withdrawn can be connected to a pressure fluid source. <IMAGE>

Title: Integrated circuit module for clock pulse switching - has shift register in circular configuration, and OR-gate in front of each memory element
Inventor: SARKOEZI IMRE DIPL ING
IPC: H03K5/135
Filed: 1989-04-24
Abstract: The switching integrated circuit contains a shift register ring of register cells (Z1-n). Each cell contains a flip-flop (Dy) coupled via an OR-gate (Gy) either directly, or via a resetting input of a series connected further OR-gate (Oy) to all other register cells, with the exception of that preceding in a shift direction. The feedback results in a H-condition only in one register cell in the shift register ring. A clock pulse monitor (2) starts the shift register ring on starting operation, then is renewed when no register cell transmits a control signal (St), due to failure. The clock pulse switching is carried out with clock pulses of identical phase spacing and frequency to one with an advanced clock pulse phase. USE/ADVANTAGE - Digital signal multiplexers, with high switching velocities and simple use. (8pp Dwg.No.4/6)
